Controllers and their features. Topics include:
• About This Guide
• About the MLC 60 Series MediaLink Controllers
• System Requirements
About This Guide
This guide provides detailed information and best practice recommendations about cabling
and configuring the Extron MLC 60 Series MediaLink Controllers. It provides reference
information about specifications, dimensions, and programming of the controllers.
Throughout this guide the general terms “MLC” and “controller” are used interchangeably
to refer to any MLC 60 Series controller. “MLC D models” applies to the MLC 62 RS D,
MLC 62 IR D, and the MLC 64 RS VC D. “MLC 62” applies to all MLC 60 Series models
except the MLC 64.
About the MLC 60 Series MediaLink Controllers
The Extron MLC 60 Series MediaLink Controllers are panels that control a wide range of
audio/video systems in any classroom, meeting facility, or auditorium via RS-232 or IR. They
act as extended remote control panels, featuring eight (optionally six) labeled backlit buttons
for the MLC 62 models or six for the MLC 64 RS VC D. These buttons can be configured
via the MLC Windows®-based configuration software to control power, input switching, and
volume on a display device or switcher. If desired, you can replace these buttons with ones
having different labels, which also are provided with the controller.
The MLC 64 RS VC D model has, in addition to the configurable buttons, a volume control
module containing an analog volume control knob and a Mute button. An Extron amplifier
can be connected to this module for volume control via the MLC.
All models can control a projector, display, or switcher via IR. In addition, the MLC 62 RS
models can control display devices, switchers, and various other items such as lights, a
projector lift, or a motorized screen via RS-232, IR, relays, or digital input.
The MLC controllers are housed in secure, compact, one-gang and two-gang sized
enclosures, which can be mounted on a wall or furniture, with or without an electrical
junction box or mounting bracket.

MLC 60 Series MediaLink Controllers • Introduction 2

The five MLC models have the same button functionality and use the same configuration
software. All models can be controlled by pressing the front panel buttons or via a host
device using RS-232 communication and simple ASCII commands (Simple Instruction
Set™or SIS™). They differ from each other in the following ways:
• The MLC 62 IR D rear panel does not contain the Relay, Digital Input, or RS-232
control ports that the RS models have.
• The MLC 64 front panel has seven buttons, one of which (the Mute button) is located
below the Volume knob. This button is used only to mute and unmute the volume on
an Extron amplifier and cannot be configured to perform other functions.
• Some front, side, and rear panel connectors are located in different places on the
MLC RS D (US), EU (Europe), and MK (United Kingdom) models (see Front and Left
Side Panels on page 10).
Faceplate alternatives
The MLC 60 Series models are available with the following faceplate configurations:
• MLC 62 IR D — The US IR model is delivered with two six-button faceplates in
black and white. One black and one white Decora wallplate are also provided. An
eight-button faceplate is available to order.
• MLC 62 RS D — The US RS-232 model is delivered with two eight-button faceplates
in black and white. One black and one white Decora wallplate are also provided. A
six-button faceplate is available to order.
• MLC 62 RS EU — The European model is delivered with six-button and eight-button
faceplates, both in white.
• MLC 62 RS MK — The UK model is delivered with six-button and eight-button
faceplates, both in white.
• MLC 64 RS VC D — The MLC 64 is delivered with seven-button faceplates in black
and white.
Features
• Customizable buttons — Eight buttons are standard on the MLC 62 RS models,
prelabeled as shown in figure 1 on the previous page. The MLC 62 IR D has six
prelabeled buttons, and the MLC 64 RS VC D has seven.
An additional set of prelabeled buttons is included with each model, enabling the
controller to be customized to suit the application.
Additional buttons are available to order for all models, labeled in English (the default)
and other languages. Buttons can be ordered with custom labeling as well.
• Button backlighting — The front panel buttons are backlit to facilitate use in
low-light environments and to provide certain status (such as whether power is on or
off, or which input has been selected).
• Alternative six-button configuration (MLC 62 RS models only) — For
applications in which input device or button functions are not necessary, the standard
eight-button faceplate on the MLC 62 RS can be replaced with a six-button one.
Each pair of source selection buttons can be changed to a long, single function
button.
• Device drivers — A wide variety of Extron certified, ready-to-use device drivers are
available via the MLC configuration software and the Extron website.
MLC 60 Series MediaLink Controllers • Introduction 3

• IR and RS-232 ports — The MLC 64 and the MLC 62 RS models each have a
dedicated serial port for communicating with most types of projectors or flat panel
displays via unidirectional RS-232. They also have an IR/S port, which can be
configured for IR or RS-232 control.
The MLC 62 IR D has only an IR port, which is used for IR communication only.
IR and RS-232 display drivers can be downloaded and used to configure the
controller.
• Relays (RS models) — Two relay ports enable control of room devices such as lights,
motorized screens, and projector lifts.
• Digital Input (RS models) — A Digital Input port enables monitoring of a switch or
sensor to control devices.
• IR Learning — The MLC can be configured by IR learning, using the remote control
of a switcher or display device to create an IR driver that enables the MLC to control
the device.
• USB configuration port — The MLC can be configured via a USB mini B port,
located on the front or side panel (depending on the model). This port can also
temporarily provide power to the MLC during configuration.
• Volume adjustment:
• The MLC 62 models have individual Volume Up and Down buttons for audio
level control, with five LEDs that indicate current audio settings.
• The MLC 64 has a volume control module with an analog potentiometer knob to
control the audio level for an Extron amplifier that is enabled for remote volume
control. The volume control module also contains a Mute button for muting and
unmuting the audio (this button cannot be reprogrammed).
NOTE: Only Extron amplifiers can be controlled via the MLC 64 volume
control module.
• Macro capability — Each button can be configured to execute multiple actions
through the serial or IR control ports. For example, a button can be configured so that
a single press triggers commands to turn on a display, select the RGB input of the
display, and trigger a relay.
• Toggling — Buttons can be placed in toggle mode, which adds flexibility by enabling
two different sets of commands to be executed with alternating presses of the button.
• Built-in speaker — A speaker provides audible feedback to confirm user actions
when buttons are pressed (except for the Mute button on the VCM module of the
MLC 64 RS VC D).
• Inactivity timer for display shutoff — An adjustable timer controls automatic
shutdown after a specified period of inactivity.
• Front panel security lockout — If the MLC is installed in an unsecured environment
where easy access is not desirable, a security lockout feature can be implemented to
lock out all front panel controls.
• Activity LED — A small LED at the top of the MLC front panel lights red, green,
or amber to indicate button presses, data transfer, front panel lockout, and other
actions.
• Section 508 Compliant — The MLC meets or exceeds accessibility standards
for Electronic Information Technology. For more information about the Extron
Commitment to Accessibility, see the Extron Accessibility web page at
www.extron.com/company/article.aspx?id=accessibility.
MLC 60 Series MediaLink Controllers • Introduction 4

Configuration Software
The MLC 55, 62 and 64 Series Configuration Program is used to configure the MLC
buttons and ports via an RS-232 or USB connection. This software, available for
download from the Extron website, enables you to set functions for the front panel
buttons and to configure the MLC ports in order to control devices via the MLC.
The software works in combination with the IR or RS-232 drivers, also provided at
www.extron.com (see Downloading and Installing the Configuration Software on
page 46 to access this program).
Device Drivers
The MLC can control a switcher, projector, or other display device via IR or RS-232
communication. The MLC must have drivers loaded for the devices it will control in order
to send commands to those devices. Drivers can be obtained in the following ways:
• You can download IR or RS-232 driver files from Extron via the driver subscription
feature within the MLC configuration program. The drivers are saved on your
computer in a folder located at c:\Documents and Settings\All Users\Shared
Documents\Extron\Driver2 or at c:\Users\Public\Documents\Extron\
Driver2. You can upload the desired drivers to the MLC using the MLC configuration
software.
• You can capture IR commands from the IR remote control of a device through
IR Learning using the MLC configuration program to create a driver that the MLC
can use. When a driver is created, it can be added to the configuration program so
that the commands can be used to configure the MLC to control the device (see the
MLC 60 Series help file to configure the MLC using IR Learning).

Front Panel Features
AActivity LED — This bicolored LED lights green when the MLC front panel buttons
are pressed. It blinks red while enabling front panel lockout (executive mode).
BDisplay power On and Off buttons — After configuring these buttons, use them to
turn the connected display device or switcher on and off.
The face of the On button contains a nub (E), which helps you to identify the button
by touch. When the On button is pressed, it blinks rapidly while the connected device
is warming up. When the Off button is pressed, it blinks slowly while the device
is cooling down. When this delay period has elapsed, the power button that was
pressed remains brightly lit. By default, only one of these two buttons can be selected
(active) at a time. Using the MLC configuration software, you can associate other
functions and relays with each of these buttons (see the configuration software help).
CVolume buttons and LEDs (MLC 62 models only) — Use these buttons to adjust
the audio volume. Each Volume button blinks when pressed and continues to blink
while being held. The volume indicator LEDs above the buttons give indications of
change to the volume level as follows:
• When the RS-232 or IR/S port has been configured with a serial driver that
contains a volume table, the five LEDs light in order from left to right to show
volume level increments.
• If the current driver does not contain a volume table, the first two LEDs on the left
blink each time the Volume Down button is pressed, and the last two LEDs on the
right blink each time the Volume Up button is pressed, indicating a volume level
decrement or increment.
MLC 60 Series MediaLink Controllers • Features, Installation, and Operation 12

DInput selection buttons — These buttons can be used to select the desired audio
or video input for the connected device or for a variety of other functions. By default
the buttons are set up as follows:
• MLC 62 RS models — Three of these buttons are set to input mode, meaning
that they are a mutually exclusive group and only one of the buttons can be
selected (active) at a time. The active input button remains brightly lit, while all
other input buttons remain dimly lit. The fourth button, labeled Mute, is set in
Toggle mode and is not grouped with the others.
• MLC 62 IR D — Two double-sized buttons are grouped in input mode and are
mutually exclusive.
• MLC 64 RS — Four double-sized buttons are grouped in input mode and are
mutually exclusive.
You can change this button behavior by using the configuration software to change
the operating mode of the button (see the MLC 55, 62 and 64 Series Configuration
Program help file for more information).
EOn button Identification nub — Power On button face contains a raised nub that
helps you to identify the On button by touch in a dark or dimly lit room.
FMute button (MLC 64 only) — Press this toggle button to mute and unmute the
volume on the Extron amplifier connected to the volume control module.
GVolume control knob (MLC 64 only) — Rotate this knob to increase or decrease
the volume on the Extron amplifier connected to the volume control module.
HReset LED — Indicates the status of a reset in progress.
IReset button — Press this reset button to initiate factory firmware or configuration
resets (see Resetting the MLC Using the Reset Button on page 43).
JUSB configuration port — Connect a USB cable (USB A to mini B) between
your computer and this port to configure the MLC via the configuration software
and to update the firmware. This port can also provide power to the MLC during
configuration.
NOTE: Do not use this port as the permanent power source for the MLC. It
should be used for power only during button and port configuration.
• On the MLC D models, the USB port is located at the right edge of the front
panel behind the wallplate. To access this port after installation, you must remove
the wallplate from the unit.
• On the MLC 62 EU and MK, the USB port is located on the left side panel. To
access this port after installation, you must detach the MLC from the installation
surface.
KIR Learning sensor — This sensor enables the MLC to learn IR commands from the
hand-held remote control of a display device or switcher. The IR-learned commands
are used to create an IR driver, then configured to be played back with any button
press (see IR Learning on page 33).
NOTE: Before performing IR Learning to create a driver, check to see if an Extron
driver exists for your device (see Obtaining Device Drivers on page 50.
MLC 60 Series MediaLink Controllers • Features, Installation, and Operation 13

Buttons
The front panel button illumination provides status on what the MLC is doing. The buttons
are lit while the MLC has power. When a button has been pressed and is active or on, it
lights brightly. While a button is inactive or off, it is lit dimly.
When buttons are grouped together, only the button that is pressed lights brightly. The
other buttons in the group remain dim. (See the configuration software help file for
information on grouping buttons. (See Downloading and Installing the Configuration
Software on page 46 to obtain the software.)
You can remove buttons and replace them with buttons having different labels. You can
then configure the new buttons with the functions that their labels represent, using the
configuration software (see the MLC 55, 62 and 64 Series Configuration Program help file
for detailed procedures for configuring the buttons).
Each Display On and Off and input selection button can be set up to perform a
sequence of several functions, which can be combinations of the following options:
• A driver operation — Execute an RS-232 or IR control command that is part of a
device driver (for a projector, VCR, DVD player, switcher, and so forth).
• A relay operation — Execute a relay command to a room device such as a
motorized screen or a projector lift.
• Setting a time delay — Insert delays between executed commands.
• Setting the button flashing rate — Specify fast or slow flashing of a front panel
button and the number of seconds the button blinks.
NOTE: While a button is blinking, all other front panel buttons are disabled.
• A user-defined RS-232 operation — Issue a non-driver-associated RS-232
command (one that you programmed separately), such as an SIS command, via the
IR/S or the RS-232 port.
• Button emulation — Initiate a series of button functions with a single button press.
